Hi, my name is JJ, my cars name is Lithium, it is a 1999 SLE I currently have underchasis light kit, HKS intake, interior neons, and I will have chip and fuel pressure regulator by the end of the week. My second house is St. Andres performance in Albuquerque NM so I get everything pretty much at cost. Need a few ideas for exhaust and plugs to go with. Hope to post many times here-after. Laterz!

Welcome JJ. Can you get us parts at cost too? I would check out http://www.clubgp.com/forum for modding info for our engines. Everyone has different opinions on what plugs to use.

Welcome to the world of the Bonneville. It is all uphill from here.. Mostly... Anyways, good to see another Bonneville owner doing something else to their car. But for you exhaust, do you want performance or try to do sound. Personally I went for performance and just said screw sound. Check out my mods and you will see.

Unfortunately I cannot milk the situation, so only I can get parts at cost, sorry, as for exhaust I want both good sound and performance to match.

I got Magnaflow, sound really good at WOT I am told. This is just the best mod I have done. I lost no low end torque and gained tons of high end power. Especially since the CAT is already 3" in and out so it now matches up perfectly. You usually cant do Flowmasters on our cars since its not a V8 so you wont get that rumble and they dont flow too well.
